I won't post any spoilers, but let's just say that it was the Hulk's coming out party. Finally he gets a film role worthy of the epic character.
Yes, they did do an amazing job with the Hulk in this movie. Normally I hate him, but this actually made me rework my ideas about him.
Like usual, there is a post-film teaser, but there is a bonus scene after all of the credits.
Yes, there was, and it was hysterical.
